ROBERT W. MCGARVEY, OF PHILADELPHIA, PENNSYLVANIA.

SAFETY RAZOR.

Application filed May 20,

To all whom it may concern:

Be it known that I, ROBERT W. MCGARVEY, a citizen of the'United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Safety Razors, of which the following is a s ecification. I

he present invention relates to safety razors.

The purpose of the invention is to provide a strong and serviceable safety razor which is'efficient in use and readily adjustable for close or coarse shaving, and at the same time has few parts, the parts being of simple design so that the entire razor may be fabricated at small expense. The razor is designed so that the blade may be stropped either manually upon the ordinary razor strop, or in a stropping' device such as that described and illustrated in my copending application Serial No. 562,488, filed May 20, 1922. A feature of the invention resides in the novel blade holding means, a holder being provided for firmly holding the blades but in such manner'that they may be easily and conveniently detached therefrom for the purpose of replacement.

In the accompanying drawings two forms of the razor are illustrated and in the following description the construction of these modifications is explained in detail, but it will be understood that the scope of the'invention is not limited to the two forms illustrated and described but contemplates that changes in design and arrangement of the component parts of the invention may be made when found convenient.

In the drawings:

Fig. 1 is a longitudinal sectional viewthrough one form of razor;

Fig. 2 is an elevation of the same as viewed from the back;

Fig. '3 is a side elevation of this razor shown in position to be stopped;

Fig. 4 is an enlarged section through the head of the razor;

Figs. 5 and 6 are plan views of the razor blade adjusting cam in two different positions;

Fig. 7 is a plan view of the blade holder with blade attached;

' Fig. 8 is a section on line 88 of Fig. 7; Fig. 9 is aside elevation ofa modified form of razor; I

1922. Serial No. 562,487.

Fig. 10 is a rear elevation of the same;

Fig. 11 is an enlarged sectional view through the head of the modified razor; and

Fig 12 is a plan view of the blade holding plate.

In the form of the invention illustratedin Figs. 1 to 8 inclusive the handle is formed from a hollow tube 10 closed at one 3 end by a plug 11 and having outwardly and oppositely curved arms 12 at its other end.

position in which it is illustrated in Fig.

4i, and in full lines in Fig. 3, to the position in which it is illustrated in dotted lines in Figs. 3 and 4. Movement of the blade holder in one direction is limited by the guard against which it directly abuts, andmovement in the opposite direction is limited by abutment of the shoulders 18 against the adjacent edges of the arms 12 of the handle. In stroppingthe razor manually on a strop such as indicated at S in Fig. 3, the blade oscillates between these two limiting stops, and the operator is enabled to sharpen the blade which is secured to the plate 16 by moving it along a strop in the usual manner, effecting the reversal of the blade holding plate by means of the fore finger which is pressed against the portion 17 of the blade holder to exert a slight'tangential force so that the rotation of this sleevelike portion and hence of the blade holder around the axle or bar 18 is effected at the termination of each stroke in the stopping operation, the blade being lifted from the strop when being reversed. I

At the ends of the blade holding plate 16 are retaining flanges 19 which extend around and over the ends of the razor blade 20 and prevent transverse movement thereof. Plate 16 is'provided centrally with a tongue 21 which is struck downwardly from the bod of the plateLand constitutes a catch whic is adapted to enter an opening 22 in the center of the blade and near its rearor it contacts with the projecting catch 21.

When the opening 22 reaches and passes over this catch, the blade snaps flat against the plate and is retained by the catch against movement away from the bar 131 its removal am he eliectetil quickly and easily by springing, upwardly its center portion with the lingers so that the catch 21 disengages the opening 22 and in then drawing the blade forwardly so that its ec disengage the retaining flanges 19. V ihsthe blade holder is mounted upon the bar 13 for tree rotation thereon it is necessary to provide means-tor locking the same in shaving position. Sleeve 17 t the-blade holder is provided with an opening. which is adapted to beengaged by the substantially c cnicail end .20 o't' a spindle 27 secured to the upper end of a plunger 28 which is slidably contained within the-handle l0 and normally pressed toward the bar 13 by means of a spring: 29. A projection 30 extending laterally fuom the plunger 28 constitutes a handleby means of which the user may rctract the plunger by means of histlnunb or finger so that the spindle 27 disengages the opening 25 to allow rotation of the blade holder, and the handle-1O is provided with a notch 31 to'receive member 30 so that the plunger may be locked in retracted position if desired byv turning the plunger so that the HiGlUbQPiiO enters the notch 31.

It will? be seen that the end 26 0f spindle 23'. tapersupwardly or is substantially conical but that the apex of the tapered portion is t(- one sideof the axis oi the spindle 27. This tapered end 26 therefore constitutes-a cam and it willbe seen that by rotating the plunger- 28 in the direction of the arrows Sand 6) from the full line position in Fig. to the full line position iniFig: 6, the apex O'fttllQCttHl will be moved tronithe 'ripjhtt toward the left, and troin this it follows thatithe sleeve 17 will be rotated. to a sh ght extent: thereby causing theblade holdc1 16 tobeunovedslightly. relatively tothe Y guard 15; This movement though slight, cnablesthe user toaregulate as he desires the dcgroeot closeness oft shaving. 1

In my copendingz applicationbefore: mentioned, is described a stropping' device: by means oft which the razor herein disclosed may beieiiicientlyf stropped by rotation. of: a handle oracrank. Forproperlypositioning the razor blade; forstroppi-ng and for holding the same; in such position-.1; have-providedin the sleeve. 17= a second. aperture 32 which. may alsobe engaged; by spindle 2.7 an thatvt-hebladeis held; in theposition in vhich;it.- is illustrated in Fig.4; pressure-of the sprin 2f) preventing disengageniicnt of the spindle from the aperture 32. The parallel slots 33 in the plug 11 are adapted to cooperate with a holding device in the stropping mechanism, to prevent rotation of the handle during-the stropping operation.

in the form of razor illustrated in Figs. 9, 10, 11' and 12 the handle is prei'ierably solid and the guard plate has a portion vhich enters a slot in the end (it the handle and 15' secured therein by. rivets 141;. The cross-bar 13 is torined'in two-portions riveted to the-parallel upwardly extending arms 15 o'l the guard plate. formed exactly as in the first descnibed form of the invention with the exception that the circular holes or apertures in the sleeve 17 of the first modification are" replaced by slots and 32 extending longi tudinallv of the sleeve 17'. A flat member or lever 35 is pivoted at 36 and the upper end of this lever is adapted to enter either of the slots 25 or 32-. When extending nithin slot 32 the blade holder is locked with the-blade in position. to be stropped in a. stropping machine, this position being shown in dotted lines in Figs 9; It will be seen from Figs. 10 and 12 that the slot 25 extends diagonally to arr element of the cylindrical sleeve 17, and in reality this slot constitutes a cam slot adapted to cooperate With lever 35 in effecting. the adjustment of theblade holding plate relatively to the guard to obtain different degrees of closeness in shaving. It will'b'e seen that inasmuch as the lever 35 swings.- about a fixed axis and in a. fixed plane,'tliat movement of this level longitudinally in slot 25 will cause rotation of the sleeve and hence movement of the cutting blade relatively to the guard. Two possible positions are shown in full. and dotted lines in: Fig. 11. Parallel transverse slots 33 are: shown at the oppositeendtof the-handle-for cooperation with the holding deviceinithe stroppi-ng n'iechanismw-ithwhich the-razor is particularly adaptedtobe used.

It will be understood that the invention is not limited to the two forms of r-azors illustratediand described but that its principles may be embodied in stillturther modifications.

Having thus described myinventio'n, What I- claim asnew and desire to'secure by'Letters Patent is: r
